C # - unable to set form.height

I have this code in a pair of button click event handlers in C # form:

class frmLogin { private const int SHORT_HEIGHT = 120; private const int LONG_HEIGHT = 220; private EventHandler ExpandHandler; private EventHandler ShrinkHandler; public frmLogin() { InitializeComponent(); ExpandHandler = new EventHandler(btnExpand_Click); ShrinkHandler = new EventHandler(btnShrink_Click); btnExpand.Click += ExpandHandler; } private void btnExpand_Click(object sender, EventArgs e) { this.Height = LONG_HEIGHT; btnExpand.Text = "<< Hide Server"; btnExpand.Click -= ExpandHandler; btnExpand.Click += ShrinkHandler; } private void btnShrink_Click(object sender, EventArgs e) { this.Height = SHORT_HEIGHT; btnExpand.Text = "Choose Server >>"; btnExpand.Click -= ShrinkHandler; btnExpand.Click += ExpandHandler; } }

Changing the text occurs without problems, but on one specific client computer, the Dell M4300 laptop workstation, the height change does not take effect. Has anyone resolved a similar problem, and what has been fixed if so?

My guess: the size of the DPI font or the system font is different on this computer, and your AutoScaleMode form is either a "font" or "Dpi", which makes your MinimumSize or MaximumSize form prevent it from changing.

Check the display mode for the laptop, and in particular, check the aspect ratio setting. Sometimes laptops do strange things to facilitate a wide, short screen.

Make sure you do not have one of these AutoScale / Size / Anyatever parameters set to true.
